What is a computer for a variety of application areas and algorithms?

A computer oriented to a variety of application fields and algorithms is a "general-purpose computer". General-purpose computers can be used in various industries and various working environments. They have high computing speed, large storage capacity, and a complete set of external equipment and software. Its characteristic is that its system structure and computer software can be suitable for different users. needs. General-purpose computers are highly adaptable and have a wide range of applications, but their operating efficiency, speed and economy will be affected to varying degrees based on different application objects.

A general-purpose computer is a computer oriented to a variety of application fields and algorithms. Its characteristic is that its system structure and computer software can suit the needs of different users.

General-purpose computers can be used in various industries and various working environments. What users in schools, homes, factories, hospitals, companies, etc. can use are general-purpose computers; the brand-name machines and compatible machines we usually buy are General purpose computer. General-purpose computers can not only do office work, but can also do graphic design, create web page animations, and search for information online.

General-purpose computers have high computing speed, large storage capacity, and are equipped with relatively complete peripheral equipment and software. But the structure is complex and expensive.

General-purpose computers are highly adaptable and have a wide range of applications, but their operating efficiency, speed and economy will be affected to varying degrees based on different application objects.

Classification of general-purpose computers

General-purpose computers can be divided into supercomputers, mainframes, medium-sized computers, minicomputers, and microcomputers according to their scale, speed, and functions. and microcontroller. The basic differences between these types usually lie in their size, structural complexity, power consumption, performance indicators, data storage capacity, instruction system and equipment, software configuration, etc.

Generally speaking, supercomputers have very high computing speeds and can execute hundreds of millions of instructions per second. They have large data storage capacity, are large in scale, have complex structures, and are expensive. They are mainly used for large-scale scientific calculations. It is also one of the important indicators to measure a country’s scientific strength. A single-chip computer is made of only one integrated circuit. It is small in size, light in weight, and has a very simple structure. Its performance is between mainframes and single-chip computers, including mainframes, medium-sized computers, minicomputers, and microcomputers. Their performance indicators and structural scale decrease accordingly.

Microcomputers, also known as personal computers, are currently the fastest growing field. It is divided into several types according to the different microprocessor chips it uses: first, those using Intel chips 386, 486 and Pentium and other IBM PCs and their compatibles; second, those using PowerPC chips jointly developed by IBM--Apple-Motorola Apple's Macintosh already has a machine using this chip; again, DEC has launched a machine using its own Alpha chip.

The difference between general-purpose computers and special-purpose computers

A special-purpose computer is a computer specially designed for a specific application field or for a certain algorithm. Its characteristic is that the system structure and special software are efficient for the designated application fields, but are inefficient or even ineffective for other fields.

The difference between special-purpose computers and general-purpose computers is that running programs generally do not need to be loaded from peripherals into memory. Instead, the programs to be executed are placed in memory in advance, and the computer starts When running, the program inside the memory will be executed according to certain rules. It rarely requires special system program control. Even if there is control, it will be much simpler than the system program of a general-purpose computer.

Special-purpose computer programs cannot be replaced, and user-written programs are not accepted, such as mobile phones, car computers, etc.

Special-purpose computers rely on a wide variety of types to meet the needs of different aspects. From a single computer, the function is relatively single. However, overall, the convergence of special-purpose computers applied to different aspects can also achieve general purpose Effect.
